Where are the deadlifts? Deadlifts are the most neglected exercises and I will never understand this. There is nothing better for endogenous gH output and testosterone than the deadlift and squat.
A deadlift is a lift and should have it's own day, but if you can't I would throw some in on your Pull day or your shoulders and delts. I could seriously write a book on just this one exercise and it's benefits.
